The number of generators providing primary frequency response in 2018 fell short of PJM’s expectations, according to the RTO’s most-recently analyzed data.

PJM’s Operating Committee endorsed manual revisions in spite of FirstEnergy's challenge to the formula for judging primary frequency response performance.

PJM will spend only $162,000 to test the winter capabilities of 21 generators totaling 477 MW in 2018, RTO officials told the Operating Committee.

A PJM proposal to revise rules on non-retail behind-the-meter generation was met with suspicion from municipal utilities and cooperatives.

NERC is still analyzing the causes of the July 10 low-frequency event in the Eastern Interconnection, PJM’s Chris Pilong told the Operating Committee.

The Operating Committee endorsed PJM’s recommended winter weekly reserve targets, which consist of monthly values based on weekly peak load.

The Mid-Atlantic region experienced heavy precipitation this summer that was great for hydro generation, PJM staff told the Operating Committee.

PJM staff outlined recommendations it developed to address a mysterious frequency drop on July 10.

PJM is hoping to simplify its communication of items that require stakeholder action through a new “stakeholder impact slide” in presentations.

PJM faced several high load forecasts and hot weather alerts last month but never had to take emergency procedures, the Operating Committee learned.
